RVP has already scored seven times in just eight appearances for the Red Devils as he heads up to Newcastle tomorrow.
Asked if the £22million summer signing could chalk up a personal best-ever tally, Ferguson said: “I would love that to happen.
“The refreshing thing for me is he has not actually had any pre-season games.
“It’s quite remarkable having seven goals from eight games. I’m pleased with that.
“I think his fitness will improve even more. I’m quite happy with what he is doing at the moment.”
